Embodiment 1

[0057] Embodiment 1 of the present invention provides a resource preemption method, and the resource preemption method is applicable to LTE, LTE Frequency Division Duplex (Frequency Division Duplex, "FDD" for short), LTE Time Division Duplex (Time Division Duplex, short for " TDD") and other systems, the embodiment of the present invention does not make any limitation on this.

[0058] Specifically, such as figure 1 As shown, it is a schematic flowchart of the resource preemption method described in Embodiment 1 of the present invention, and the resource preemption method may include the following steps:

[0059] Step 101: For any cell, determine the amount of resources to be released by the cell when the bearer to be preempted in the cell is successfully preempted, wherein the bearer to be preempted is a request for access and has not been successfully accessed due to limited cell resources. incoming bearer.

[0060] Specifically, in the embodiments of the present invention...

Embodiment 2

[0097] The resource preemption method in Embodiment 1 of the present invention will be further described below in combination with specific embodiments.

[0098] Assume that the basic information of each accessed user terminal / accessed bearer in the cell is shown in Table 1 (wherein, each accessed user terminal is numbered from A to G, and each accessed bearer is numbered from 1 to 10, and the connected user terminals B, C, and D each contain two connected bearers), and assuming that the upper limit of the access control load rate of the cell is 0.9, the load rate requirement of the bearer to be preempted is 0.18, and the load rate of the bearer to be preempted is The ARP preemption priority value is 5.

[0099] It should be noted that the priority information of each accessed bearer or bearer to be preempted (including the ARP preemption priority value and whether it can be preempted, etc.) can be determined in advance through ARP parameters. The rate can be determined in ad...

Embodiment 3

[0139] Embodiment 3 of the present invention provides a resource preemption device, and the resource preemption device is applicable to systems such as LTE, LTE frequency division duplex, and LTE time division duplex, which is not limited in this embodiment of the present invention.

[0140] Specifically, such as Figure 4 As shown, it is a schematic structural diagram of the resource preemption device described in Embodiment 3 of the present invention. The resource preemption device may include a resource amount determination module 11, a user terminal determination module 12, and a user terminal switching module 13, wherein:

[0141] The resource amount determining module 11 is used for determining, for any cell, the amount of resources that the cell needs to release when the bearer to be preempted in the cell is successfully preempted, wherein the bearer to be preempted is a request for access and is determined by the cell A bearer that is not successfully accessed due to r...

Abstract

The invention discloses a method and equipment for resource preemption. The method comprises the steps of determining a resource amount required to be released by a cell (any cell) when a load to be preempted in the cell is successfully preempted, and when the condition that the sum of resource amounts capable of being released by all switchable user terminals in the cell is not smaller than the resource amount required to be released by the cell (any cell) when the load to be preempted in the cell is successfully preempted is determined, sequentially switching each switchable user terminal according to an ascending preemption priority level sequence until the total released resource amount obtained after switching is not smaller than the resource amount required to be released by the cell (any cell) when the load to be preempted in the cell is successfully preempted. According to the method and the equipment, during the resource preemption, a terminal switching strategy is considered in a priority manner, and the current business of each terminal can not be interrupted when each terminal is switched, so that the problem in the prior art that the business call drop rate is relatively high caused by the fact that a forced release manner is adopted during the resource preemption can be solved, and then, the effects of lowering the business call drop rate and improving the customer satisfaction are achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource preemption method and equipment applicable to an LTE (Long Term Evolution, long term evolution) system. Background technique [0002] Resource preemption mainly refers to the technology to ensure that some high-priority users can access the network by releasing some resources occupied by low-priority users when the network is congested. Resource preemption technology can be used in both wired and wireless networks, especially in wireless networks, because the wireless channel is dynamically changing, so the capacity of the channel and the wireless resources that users need to occupy are also dynamically changing. Therefore, resource preemption Facing greater challenges. [0003] Specifically, in wireless networks such as the LTE system, resource preemption can be performed in a forced release manner, for example, by using the user's ABR (Access Bi...
